What is the supplementary angle of 137 degrees? Here we will define the supplementary angle of 137 degrees, show you how to calculate the supplementary angle of 137 degrees, and even illustrate the supplementary angle of 137 degrees (137°) so you have a solid understanding of what it means.
The supplementary angle of 137 degrees, also known as the supplement angle of 137 degrees, is the angle that when added to 137 results in a sum of 180. Therefore, to calculate the supplement angle of 137 degrees, we subtract 137 from 180. Here is the formula, the math, and the answer:
180 - angle = supplement angle
180 - 137 = 43
43 degrees
137 degrees plus the supplementary angle of 137 degrees equals 180 degrees, which means that together they will make a straight line.
The illustration below shows 137 degrees colored in red and the supplementary angle of 137 degrees, which is 43 degrees, colored in green.
As you can see from the illustration above, 137 degrees and 43 degrees form a straight line together. This proves that the two angles, 137 degrees and 43 degrees, are supplementary angles.
